From 7edab2f0876ff6a38e10a88c9aca20180aad307c Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Tue, 17 Oct 2006 10:17:58 -0700 Subject: [PATCH] pci/i386: style cleanups Mostly CodingStyle cleanups for arch/i386/pci/i386.c: - fit in 80 columns; - use a #defined value instead of an inline constant; Also change one resource_size_t (DBG) printk from %08lx to %lx since it can be more than 32 bits (more than 8 hexits).
